This is an Unreal Engine project that uses a custom material and blueprint to display the Stanford Bunny as a point cloud, using the technique created by xnihil0zer0 and described in this Unreal forum thread.
This method uses a bitmap image derived from the point cloud as a lookup table to position the individual particles.
Many thanks to xnihil0zer0 for creating this technique, and for the kind and patient assistance in getting my version of it working.
